Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a pollution-resistant porcelain insulator. Background Art

[0002] Porcelain insulators are used for insulation and fixing conductors in high-voltage overhead transmission and distribution lines. Generally, they are assembled into insulator strings for use on lines of different voltage levels. Common porcelain insulators are usually assembled by cementing porcelain parts, iron caps and steel feet with Portland cement No. 525 or above, porcelain sand or quartz sand cement. The upper surface of the porcelain insulator is usually large and smooth, with a relatively large flat surface having a gentle slope. When there is a heavy rain or a downpour, rainwater may first accumulate on the upper surface of the porcelain insulator. When the rainwater accumulates to a certain extent, it will slide downwards. Moreover, due to its gentle slope, the rainwater forms a chain-like shape when falling, and continues to fall, which is likely to cause rain flash and increase the potential safety hazard.

[0003] In addition, when exposed to the outdoors for a long time, the gentle upper surface of the porcelain insulator is extremely easy to accumulate dust. When the rainfall is small, the rainwater slides down from the upper surface of the porcelain insulator at a relatively slow speed, and its falling speed cannot carry away the dust accumulated on the upper surface of the porcelain insulator, and may even leave stains on the upper surface of the porcelain insulator.

[0004] Therefore, how to design a pollution-resistant porcelain insulator that can solve the above technical problems is a technical problem to be solved. Summary of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a pollution-resistant porcelain insulator, which increases the slope of the upper surface of the porcelain insulator, so that rainwater can be dispersed as much as possible to form a chain-like shape during heavy rain, and at the same time increases the sliding speed of rainwater during light rain, and takes away the dust accumulated on the surface of the porcelain insulator as much as possible through the rapid falling of rainwater.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: comprising an insulator intermediate shaft, an insulator shed fixedly sleeved on the outer peripheral wall of the insulator intermediate shaft, and an anti-fouling component detachably arranged on the umbrella surface of the insulator shed; a first connecting ring groove is opened on the upper end surface of the insulator shed near the periphery of the insulator intermediate shaft, the anti-fouling component comprises a connecting shed that matches the shape and size of the first connecting ring groove, and an anti-fouling shed detachably arranged on the upper end surface of the connecting shed and arranged at an angle staggered with the connecting shed; the connecting shed is composed of a plurality of first fan-shaped units connected and enclosed on the left and right, and a low square is formed between adjacent first fan-shaped units. A first saddle for rainwater to slide down; a plurality of connecting blocks are arranged at the bottom of the first connecting annular groove, and a connecting groove is provided on the lower end surface of the connecting umbrella skirt corresponding to the position of the connecting block in the first connecting annular groove; a second connecting annular groove is also provided on the upper end surface of the connecting umbrella skirt along its circumference, and a plurality of connecting blocks are arranged at the bottom of the second connecting annular groove; the anti-fouling umbrella skirt is composed of a plurality of second fan-shaped units connected and enclosed on the left and right, and a low second saddle is also formed between adjacent second fan-shaped units; a connecting groove is provided on the lower end surface of the anti-fouling umbrella skirt corresponding to the position of the connecting block in the second connecting annular groove; the second fan unit and the first fan unit are arranged at a staggered angle.

[0007] Furthermore, the height of the connecting shed is higher than the height of the first connecting ring groove, the height of the connecting shed from one end of the intermediate shaft of the insulator to the edge of the connecting shed decreases successively, and the length of the top of the connecting shed is longer than the length of the first connecting ring groove.

[0008] Furthermore, the height of the anti-pollution umbrella skirt is higher than the height of the second connecting ring groove, the height of the anti-pollution umbrella skirt from one end close to the intermediate axis of the insulator to the edge of the anti-pollution umbrella skirt decreases successively, and the length of the top of the anti-pollution umbrella skirt is longer than the length of the second connecting ring groove.

[0009] Furthermore, the angle between the second fan-shaped unit and the first fan-shaped unit differs by 90°, and the backbone of the second fan-shaped unit is directly opposite to the first saddle between the adjacent first fan-shaped units below.

[0010] Furthermore, the cross-sections of the first sector unit and the second sector unit are both arc-shaped with a high middle and concave sides.

[0011] Furthermore, the length of the second fan-shaped unit is smaller than that of the first fan-shaped unit.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a connecting umbrella skirt and an anti-pollution umbrella skirt, which are respectively composed of a first fan-shaped unit and a second fan-shaped unit connected side by side. The cross-sections of the first fan-shaped unit and the second fan-shaped unit are both arc-shaped with concave sides and a high middle. At the same time, the anti-pollution umbrella skirt and the connecting umbrella skirt are arranged at an intersecting angle. When rain drops, the rainwater easily slides quickly from the middle of the second fan-shaped unit to both sides. Due to the difference in the falling positions of the rainwater, the rainwater scatters to the saddle parts on both sides. When it falls from the second fan-shaped unit to the first fan-shaped unit, it is scattered by the first fan-shaped unit, avoiding a large amount of rainwater dripping onto the same saddle part during heavy rain, resulting in the formation of a chain of rainwater and reducing the possibility of rain flash.

[0014] 2. The utility model sets the heights of the first fan-shaped unit and the second fan-shaped unit to gradually decrease from the middle to the edge, increasing the inclination angles of the first fan-shaped unit and the second fan-shaped unit, accelerating the sliding of rainwater and avoiding the accumulation of rainwater on the upper surfaces of the connecting umbrella skirt and the anti-pollution umbrella skirt, thus causing adverse reactions.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present utility model in detail with reference to the drawings and specific embodiments:

[0022] See Figure 1-2 As shown, the solution includes an intermediate shaft 1 of the insulator, an umbrella skirt 2 of the insulator fixedly sleeved on the outer peripheral wall of the intermediate shaft 1 of the insulator, and an anti-pollution component 3 detachably arranged on the umbrella surface of the umbrella skirt 2 of the insulator;

[0023] The upper end surface of the insulator shed 2 is provided with a first connecting ring groove 21 near the insulator intermediate shaft 1. The anti-fouling component 3 includes a connecting shed 31 that matches the shape and size of the first connecting ring groove 21 and an anti-fouling shed 32 that is detachably arranged on the upper end surface of the connecting shed 31 and arranged at an angle staggered with the connecting shed 31; the connecting shed 31 is composed of a plurality of first fan-shaped units 311 connected and enclosed on the left and right, and a low first saddle 312 is formed between adjacent first fan-shaped units 311 to facilitate rainwater to slide down; a plurality of connecting blocks 211 are provided at the inner bottom of the first connecting ring groove 21, A connecting groove 313 is provided on the lower end surface of the connecting umbrella skirt 31 corresponding to the position of the connecting block 211 in the first connecting ring groove 21; a second connecting ring groove 314 is also provided on the upper end surface of the connecting umbrella skirt 31 along its circumference, and a plurality of connecting blocks 3141 are provided at the bottom of the second connecting ring groove 314; the anti-fouling umbrella skirt 32 is composed of a plurality of second fan-shaped units 321 connected and enclosed on the left and right, and a low second saddle 322 is also formed between adjacent second fan-shaped units 321; a connecting groove 323 is provided on the lower end surface of the anti-fouling umbrella skirt 32 corresponding to the position of the connecting block 3141 in the second connecting ring groove 314;

[0024] The second fan-shaped unit 321 is staggered with the first fan-shaped unit 311. Furthermore, the second fan-shaped unit 321 is 90° different from the first fan-shaped unit 311. The backbone of the second fan-shaped unit 321 is directly opposite to the first saddle 312 between the adjacent first fan-shaped units 311 below.

[0025] Further, the height of the connecting shed 31 is higher than the height of the first connecting ring groove 21, the height of the connecting shed 31 from one end close to the insulator intermediate shaft 1 to the edge of the connecting shed 31 decreases successively, and the top length of the connecting shed 31 is longer than the length of the first connecting ring groove 21, thereby reducing the possibility of rainwater infiltrating into the first connecting ring groove 21. The height of the anti-fouling shed 32 is higher than the height of the second connecting ring groove 314, the height of the anti-fouling shed 32 from one end close to the insulator intermediate shaft 1 to the edge of the anti-fouling shed 32 decreases successively, and the top length of the anti-fouling shed 32 is longer than the length of the second connecting ring groove 314, thereby reducing the possibility of rainwater infiltrating into the second connecting ring groove 314, and at the same time, facilitating the flow of rainwater to the outer edges of the connecting shed 31 and the anti-fouling shed 32, thereby accelerating the flow of rainwater.

[0026] The cross section of the first sector unit 311 and the second sector unit 321 is an arc shape with a high center and concave sides, so that rainwater can flow from the first saddle 312 and the second saddle 322 on both sides of the first sector unit 311 and the second sector unit 321 .

[0027] Furthermore, the length of the second fan-shaped unit 321 is smaller than that of the first fan-shaped unit 311 .

[0028] The working principle is generally as follows:

[0029] When it rains, rainwater slides from the ridge of the second fan-shaped unit 321 towards the second saddle 322. At the same time, since the height of the anti-fouling umbrella skirt 32 decreases from the inside to the outside, the rainwater slides down along the second saddle 322 towards the first fan-shaped unit 311. After the rainwater drips onto the first fan-shaped unit 311, it slides towards the first saddle 312 at the junction and then slides down along the first saddle 312, avoiding the accumulation of rainwater during heavy rain and causing adverse reactions.

Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
